PULLING-OVER MACHINE.

Patented J line 28, 1921.

Application filed. May 31; 1919. Serial No. 300,852.

T 0 all whom it may concern Be it known that I, VILLIAM; C. STEWART, a subject of the King of England, residing at Swampscott, in the county of Essex and. State of Massachusetts, have invented cer-' tain Improvements in Pulling-Over Ma-.

in the manufacture of boots and shoes for.

pulling uppers over lasts, and is herein illustrated in its application to a well known type of pulling-over machine characteristic features of which are shown and described in United States Letters Patent No. 1,029,387

granted on June 11, 1912, uponan application of R; F. McFeely. It will be understood, however, that the invention is not limited in utility to the type of machine shown in said patent but is broadly applicable to varioustypes of construction.

The invention provides important improvements in pulling-over machines in respectto provision of means for locating the tip line in thecorrect relation to the last, and means for tensioning the upper properly lengthwise of the last. In the machine herein shown at the correct distance from the end of the last is insured andthe upperis tensioned along the sides by apredetermined relative movement of the upper and the last inua direction lengthwise of the last while the side grippers hold the margin of the upper.

More particularly, the illustrative machine has means whereby the side grippers may be closed initially upon the upper in a definite relation to the opposite ends of the tip seam and means for imparting to the toe gripper a rearward movement of predetermined extent while in contact with the toe end face of the last to push the last rearwardlywithin the upper the required distance to give the proper length oftip. moreover. the upper along the sides of the shoe is tensioned lengthwise from the heel endtorwardly, and the end portions of the tip seam are so positioned with reference to the subsequent forward pull on the middle portion 01": the seam by the toe gripper asto the location of the tip line By this operation,

prevent bowing ot the tip line. Important features of theinvention; are to be recognized tin-the novel organization whereby the desired results as to length of tip, straightness of the tip line, and lengthwise tensioning of the upper are secured.

A further feature of the invention consists in novel means for insuring the correct angular relation of the tip line to the longitudinal medial line of the shoe. To this end the illustrative machine has means whereby the opposite side grippers may be positioned 1n a predetermined relation lengthwise of the last, combined with heel rest positioning means deslgned to determine a corresponding definite lateral swing of the heel part of the last. 'A further advantageous characteristic of the novel con:

struction shown resides in its adaptability to qulck and accurate reversal in changing between right and left shoes.

The above and other features of the invention, including novel side gripper adusting means,'novel means for ad usting and controlling the toe gripper, novel means for adjusting the limit of lateral movement of the heel rest, and various details of construction and combinations of parts, will now be described with reference to the ac-- companying drawings and pointed out in' the claims. 1

Machines of the general type illustrated comprise in their organization a gripperfor engaging the upper at the toe end ofthe last and grippers for engaging the upper at the opposite sides of the forepart. The side grippers in the. construction herein, shown comprise two pairs of upper gripplng aws 2 at each side, these jaws being mounted and'operated similarly to the construction shown and described in detail in United States Letters Patent No. 1,030,522, granted jon June25, 1912, on an application of R. F.

M'cFeely, although it is to be understood that .the utility of the invention is not dependent" upon the use of a duplex constructionofthis character. T he gripper jaws at each side of the machine, as shown in said patent, are mounted on a gripper casing 4, comprising a separately movable part for each pair of jaws, and are first closed and then operated to pull the upper by lengthwise movement of a, gripper bar 6 connected to van updraw lever 8 which is pivotally mounted on 'the frame of the machine.

"When the machine stands idle the, gripper I bar 6 and the casing sections 4 are relatively so disposed, 1n consequence'of engagement of shoulders 10; on the casing sectlons with ii portions 12"of the frame through which the gripper is. guided", as to relieve the gripper jawsfromthe-action of their closing springs (not shown). It will be understood that after the work has been properly positioned the first portion of the movement of the bar 6. renders thesprings effective to close the jaws upon the'up'per and that as the bar continues its movement the casing sections and the jaws are moved withit to pull the up a per. The gripper levers 8 are operated by means of a cam on a cam shaft 14fthrough a slide""16 which carries rods 18 encircled by springs 20 which bear upon the rear end portions of the gripper levers, the springs being compressed as the slide is moved downward and the grippers thus operated to pullthe upper yieldingly. The toe gripper comprises a pair of aws 22 carried by a gripper casing '24,.this gripper being operated through a bar 25 similarly to the side grippers to 'closeupon the upper and-then to pull it by means of an updraw lever26 yieldingly connected through a rodandfa spring to a cam slide 28 operated by a cam on the cam shaft 14.; p I

The machine is controlled bythe usual starting treadle whereby upward movement is'. imparted. to a treadle rod 30 against the tension of a spring 32, the upper end of this rod engaging a slide 34-wherebythe clutch '(not shown) is actuated through a clutch rod 86 to cause movement to be imparted from the main driving shaft to-the' pulley 38 on the cam 'shaft 14., For a more complete understanding of the details of this construction reference may be made to prior" Patent No. 791,986, granted on June 6, 1905,

on applicationof R. F. McFeely. Upon thefirst actuation of the 'clutch theftoe and side grippers are operated asabove described to pull the upper, the last being held against the pull of the grippers by means of-sole rest 40 against whichthebottomofthe sole or insoleis positioned when the work is presented to the machine, this sole rest also receiving a shortfdownwarc'l rocking movement'to depress the last within the upper, as usual in this type of machine. As, the upper pulling operation is effected, a heel rest 4 2havingdivergent portions constructed partially toembrace the heelend of the shoeis moved up yieldingly intosuppo'rting and herein provided eliminatesthenecessity for such, inspection and adjustment as have been necessary heretofore as far as concerns length of the tipv and the angular relation of the tip line to the last.

lVhen the machine is again started side clamp arms 43 are moved laterally int-o supporting and holding engagement with the shoe and the margin of the upper is wiped inwardly at the toe end and atthe opposite. sides ofthe last and secured in place by wiping and-tacking mechanisms which are carried'by front tacker arm 44 and side tacker arms 46. Theoperative inward movement of the front and side tacker armsis permitted through provision for inward movement of the toe and side grippers when released by their controlling means, the side grippers being movedinwardly tosome extent by overdraw springs 48 (Fig. 2) which details.

' such marks As the last and the upper engage a plate 5.0 that bears on the outer sides of the casing members at, and the toe gripper by similarsprings 52 1). A latch 54L on the 'toe gripper and latches 56 on the side grippers are engaged by the corresponding inwardly movable tackenarms i l-and $6 to cause the grippers finally to release the upper, the tacks being then driven and the parts of the machine re-- turned to startingpositlon.

Since the general organization of the machine, except as modified for the purposes of this invention as hereinafter explained may be andis herein shown as conformable substantially to the disclosure of thelprior McFeely patents above mentioned any furtherdeseription of i the details of construction of such general features may be dispensed with and reference may be made to said prior patents for any further desired information as to such it is contemplated that for the purposes of this invention the lengthwise positions ofithelastand of the upper will be deter--' when the work is presentedto'the machine, and to this end the toe gripper is so disposed as to permit the toe end face of'th'e last to be positioned in mined independently engagement with the rear toe gripper jaw to the gripper casing and which is fixed the front pair of'side gripper jaws2 at each side of .the last is provided with a. mark 58 to indicate the correct-location of the tipseam or tip line. It will be understood however, that the correct location of the opposite ends of the tip seam relatively to the side grippers may tion shown beingeffected manually by a movement of the treadle rod before the.

By reference to Fig. 1 it clutch is tripped.

as the machinestands idle will be seen that a space is provided between the rear ends of the side updraw levers 8 and the top of the cam slide 16, the rear ends of the levers be ing held up against their operating springs 20 by means of additional .springs60 connected at their lower'ends to pins 62 which project laterally from" the gripper levers and at their upper ends'to studs 64 secured at the opposite ends of a plate 66 which extends across the tops of-the tension adjusting nuts 68 on the gripper. operating rods 18. Thepins 62 extend through slots in de pending links 70 which are connected at 0 their lower ends to hell crankarms 7 2, these distance relatively to the upper the upper in the side:

arms having rigid connection with a forwardly extending arm 74 connected by a rod 76 to a clamp 7 8 on the treadle rod 30 Between the upper end of the rod 80 and the clutch tripping slide 34a space is provided to permit a substantial extent of upward movement of the rod before the clutch is tripped. By such initial movement ofthe rod 80 the links 70 are operated through the rod 76 and the hell c'ank arms 44: an l72 to pull the rear ends of the side updraw levers 8 downwardly and thus to operate the gripper bars (3 in such manner as to permit the gripper jaws to be closed upon the upper by their closing. springs. Correct location of the upper in the jaws is by further movement of the rod 30, which may or may not be continuous with its initial movement theclutch is tripped and the .machine is started. 3

The first movement imparted to the toe gripper upon the a rearward-swinging movement to cause it by engagement with the end face of the last to push the last backwardly a predetermined held by the side grippers. For this purpose the machine is provided with a cam 80 fast on a camshaft 82 which carries a pinionSi engaged and driven by pinion 86 on a shaft 88which is conveniently formed asan extension ofa shaft provided in machines of this type as a support forspeedreducing gearing 90' (Fig. 1) between the pulley 88 and the mam cam shaft let, the pinions 84: and 86 be1ng so proportionedthat the cam 82 is rotated at thesame rate as the main cam shaft 14. Engaging the face of the cam 80 is a roll 92 carried by a pivoted lever 9 which-is connected at its upper end by means of a link 96 to, a crank arm 98 on av rock shaft thus insured. and

starting of the machine 1S 7 100 mounted in bearings in a bracket 1052 secured on the front of the frame of the machine. Fast on the shaft 100 is a crank arm 10a uponthe outer end ofwhich is pivotally mounted a frame member comprising two arms 106 one of which is provided with a slot 108 to receive aguiding pin 110 on the frame of the machine. The arms 106 extend rearwardly toward the toe gripper and are provided at their rear ends with plugs 112 which have slots in their inner secured on thefront of the gripper caslng 24. As the machine stands idle the opposite side edges of the platellet are within the slots in the plugs, as shown 111 Fig. 2', and

lengthwise of A spring 116 of the lever 94:

the position of the gripper the last is thus determined. connected to theupper end tends to swing the lever in a direction to hold its roll 92 in engagement with the cam andthus' maintains the toe gripper yieldingly in its initial position. hen the machine is started a rise a on the cam 80 en- 7 ends to receive the opposite edges ofa plate 114:

gages the roll 92v and operates the lever 94 I and the connected parts to move the arms 106 rearwardly and thus to cause the .toe

' gripper to push the last backwardly in the upper to tension theupper along thesides' and to locate the end face of the last at the correct distance from the ends of the tip seam held by'the front pairs of side gripper jaws. The initial position of the toe gripper and thelimit of its rearward movement in engagement with the last are determined by an adjustable connection between the rock shaft and the arm 98, comprising a worm 118 journaled in a bracket120 fast on the rock shaft and engaging the teethofa gear segment 122 which is integral with the arm 7 98 By turning the worm 118 the rockshaft rect length of tipthrough the automatic op eration' above described, consideration must be given both to the standard length of tip.

for'the particular style of, shoe upon which the machine is to operate and to the size of,

the shoe, since the length ofthe tip not only varies with the size but may vary also in differentstyles of thesame size The machine is further provided with means for determining the correct adjustment of the worm 118 with regard to both these variables. By reference to Fig. 2 it will be seen that: the wheel 124 carries on its front face a series of numerals any one of which may be presented in'view through a hole 126 in an adjustable segmental plate 128 which is fast on a spindle 130' (Fig; 6) extending, centrally through the worm118 and provided at its rear end'with a spring 132 which tendsto hold the plate against the faceof the wheel with apin 134 on the platein engagement in one of a series of holes inthe face of'the wheel, there'being one hole for each of the numerals. A knob 136'projecting from the plate-128-pe1'mits the plate to be pulled out-' 7 wardly from the wheel 124 against the'ten- 'sion of the spring 132 and turned'to bring the hole 126 over any one of'the series of numerals on the wheel. These numerals, which 'may or may not be arbitrary symbols, indicate different standard lengths of tip correspending to different styles of shoes. The

plate 128 carries on its marginal edge a plurality of marks 138 which indicate shoe sizes, these marks being located opposite to numerals correspond ng to the different s zes.

On the bracket 120 is a projection14O on which is a, mark 142 arranged to register with one or another of the size marks 138. Havingadjusted-the plate 128 relatively to the wheel 124 in accordance with the style of shoe the-operator turns the. wheel '124 to bring the mark indicating the size of the shoe upon which the work is to be performed into registration with the fixed mark 142.. The corresponding turning movement of the worm 118 adjusts the toe gripper in the manner hereinbefore described for thelength of tip on the style and size of shoe in question,

and the'toe gripper having been thus-adjusted the toe end face of'the last at the' limit 'of its rearward movement will belocated precisely at the required distance from the ends of the tip seam held in predetermined relation to the side gripper jaws. It will'be-evident that such adjustment is automatically maintained during the time that the machine is to operate upon shoes vof the same style and size, and that when a change is to be made in the character of the, work the proper readjustment of the toe gripper may be'quickly and accurately effected. v It will be understood that following the backward movement of the toe gripper its updraw movement is effected bythe operation of the lever 26in the manner usualin machines of this type, such movement of j thegripper being permitted by the sliding connection between the plate 114 and the plugs'112. Near its lower end the plate 11.4 is cut inward on each side, as indicated at 144, and each of the plugs 112 is cutaway at its rearside, as indicated at 146. iThis construction permits the releaseof the toe gripper from control of the plugs 112 berelease taking place when the narrower ;lower portion of the plate arrives in position between the cut back rear portions-0f the plugs. The toe gripper overdraw. spr ngs 52 are then'permitted to operate toeswing the gripper rearwardly out of control of the :arms 106 as indicated in=Fig-.f4,, the gripper thus overdrawing the upper and subsequently moving out of the way of the overwiping and-tacking mechanism.

10o :fore'it completes its updraw movement, such 1 Return .of the toegripper into position to cause the plate 114'again m enter the slots in the plugs'1'12 is'eifected bymechanism shown iniFig. 7.. 1 This imechanism comprises a bar 148 which carries on its front end a roll 150 in engagement with the rearside of the toe gripper bar 25. Forward movement is imparted to this barto return the toe gripper through a spring by a pinion- 156 on a shaft 158 mounted in bearings inthe frame'of the=machine. On one end of the shaft 158 is acrank arm 160 which is connected by" a link 162 to a pivoted'lever 164 carrying at its lower end a 'roll 166 arranged to be engaged and oper ated'by a cam 168 on the face of the pinion 84. A spring 170 connected to the lever 164 .7

tends to swing the lever in'a direction to 12 0, 152 from a rack bar 154 which is operated hold theroll 166 operative relation to the cam and serves also, when the campermits, to operate the link 162 and the crank arm 160 to turn the shaft 158 in a direction to withdraw the bar 148 from thetoe gripper bar 25. By reference to Fig. 13 it will be seen that such withdrawal of the bar 148 takes place immediately upon the starting of the machine, thus permitting the toe gripper to be swung backward by its connections to the cam 80 in the manner hereinbefore described.

It will also beseen by reference to Fig. 7 that the bar 148 carries means for determining the spacing of the side grippers, comprising a wedge block 172 provided on its opposite sides with inclined faces in engagement with rolls 174 on pivoted lever arms 176 which carry blocks 178 having bearing contact with the inner faces of the side gripper bars 6. In the present construction the wedge block 17 2 is adjustable lengthwise of the bar 148 to space theside grippers diflerent distances apart for different sizes of shoes, the block being connected by means of a rack bar 180 to a pinion 182 formed on a sleeve 184 which-is normally connected by means of a toothed clutch 186 to the shaft 158. By engaging a handwheel 188 on the end of the sleeve .184 and moving the sleeve endwise against the tension of a spring (not shown) the sleeve may be dis connected. from the shaftand then turned to adjust the wedge block relatively to the bar 148. It will be evident that this gripper spreading mechanism comprising the wedge block 172 and the bar 148, in its broad features is similar to mechanism heretofore provided in machines of-this general type, as shown in Patent No. 1,029,387J In the construction herein shown, however, the wedge block 172, normally connected as it is through the clutch teeth 186 to the shaft 158, is moved backwardlywith the bar 148 immediately after .the machine is started, and therefore the side grippers are released to the act-ion oftheir overdraw.springs 48 earlier than in prior constructions, thus causing the side grippers to move inwardly as far as permitted by the last or by the tension of theupper during their updraw. In the return of the parts to starting position the shaft 158 is turned bythe action of the cam 168 to more the bar 148Iand the wedge block forwardly and thus to move the toe gripper yieldingly forward until the narrow portion of its plate 114 engages the longer front end. portions of the plugs 112, thus alining the plate 114 with the slots in the plugs and causing the plate toenter these slot-s as the toe gripper is then moved downwardly. Simultaneously the side grip.- persv are moved apart bythe. action of the wedge block 172 and positioned properly for engagement with the next shoe,

' It will be understood that in aproperly made shoe the tip line extends across the shoe substantially at right angles to thelongitudinal median line of the forepart. If

it were feasible therefore'to present each shoe to the machine with the longitudinal median line of the 'for-epartextending perpendicularly to the rear face of the toe gripper jaw, the proper locations for the side grippers would be such as to position the tip seam marks 58 at the opposite sides equal distances rearwardly from the plane of the toe gripper face. Since, however, in modern lasts the longitudinal median line of the heel part extends at a decided angle to the corresponding line of the forepart, this angle representing what is termed the swing of the last, it is not usually feasible to present the work in the above-mentioned relation to the toe gripper, since if this were done the heel part of the last would project laterally too far to permit the heel rest properly to engage and position the shoe. It is contemplated therefore thatthe work shall be presented to the machine herein shown with the longitudinal median line of the forepart inclined to the rear face of the toe gripper in a manner partially to compensate for the lateral swing of the last, such line of course being inclined toward one side of the machine for a right shoe and toward the other side ofthe machine for a left shoe. This necessitates that one of the side grippers be positioned nearer than the other to the toe gripper for one of the shoes of a pairand that the positions of the opposite side grippers be reversed when the machine is to operate upon the other shoe of the pair. For this purpose the machine is provided with side gripper adjusting mechanism which, as shown in Fig. 8, comprises some of the --characteristic features of similar mechanism illustrated in Patent No. 1,029,387. By reference to 8, and by further reference to said patent, it will be .icn that one of thel side grippers is connected to aslidable rack bar 190 engaged by a pinion 192 on a transverse adjusting shaft 194,.and that the other gripper is connected to a similar rack bar 196 engaged by a pinion 198 fast onsaid shaft, the rack bars being connected to the respective side grippers by means which permits the grippers to have their characteristic updraw and overdraw movements. It will be seen that the rack Jar 190 extends underneath the pinion 192,

while the bar 196 extencsover the pinion 198, and therefore that by rotation of the shaft 194 movements are imparted to the respective side grippers lengthwise of the shoe simultaneousiyin opposite directions. For turning the shaft to adjust the grippers the machine is provided with a handle 200 which by movement in one direction adjusts the grippers for a right shoe and by movemellt in the opposite direction adjusts them i for a left shoe.

In order to save time for the operator in,

determine the different locations of the grippers for the right and left shoes of that style. This mechanism comprises a pin 202 mounted eccentrically atone end of the shaft 194 to turn with the shaft and an adjustable limiting member 204 pivotally mounted on a 7 pin 206 on a bracket 208- andprovided with v erence to Fig; 9 that the walls of the guidea substantially V-shaped recess or guideway 210 between the opposite walls of which the pin 202 is located. It will be evident by refway210 positively limit turning movement of the shaft 194 in both directions and that as the member 204 is adj usted'about its pivot the extent of such possible movement of the shaft is varied, the relation between the pin and the guideway being such that any increase or decrease in the range of movement of the shaft in one direction is accompanied by a corresponding increase or decrease of equal extentin the opposite direction. With the member 204 properly adjusted for the style of shoe in question, the side grippers are properly positioned to operate, for example, upon a right shoe of that style when the handle 200 is moved as far in one direction as is permitted by engagement of the pin 200 with one of the walls of the guideway 210, and all that the operator is required to do in order to readjust the side grippers for a left shoe of that style is to move the handle 200 as far in the opposite direction as the limiting means permits. Obviously such adjustments may be very quickly efi'ected without need for any partlcular care upon j the operators part. Further 'to facilitate such adjustment and to assist in maintaining the grippers in adjusted position, the handle 200 carries aspring pressed pin 212 the inner end of which is held in engagement with a guide member provided with surfaces 214 which slope in opposite directions from a central high point. The pin 212 may be pullcd'outwardly if desired by means of a controlling lever 216 to which it is connected. It is contemplated, however, that the tension of the spring pressed pin will be suchthat the-operator may conveniently swing the handle to move the pin past the high point onits guide without the necessity for withdrawing it. It will be evident that the slop ing surfaces 214, by wedging engagement with the pin 212, tend to swing the handle in one direction or the other in such manner as to hold the pin 202 against the corresponding wall of its guideway, the construc: tion thus not only permitting precise adjustment of the grippers in the" manner deter mined by the guideway 210, but also serving to maintain thecgrippe'rs in adjusted position. 7 By reference to Figs. '8 and 9 it will be seen that the member 204 is provided with" an 'arcuate series of depressions 218 arranged to be engaged by aspring held plug 220 to maintain the limiting member in different positions of adjustment.

In order still further to insure the proper angular relation of the tip line to the last, the machine is provided with means for determining accurately the angular .position of the last relatively to the plane of the rear face of the toe gripper, comprising mechanism for determining different limits of lateral displacement of the heel rest 42. It will be recognized that, similarly to the constructionshown in Patent No. 1,029,387,

inclined side portions which'are arranged partially to embrace'the heel end of the shoe and thus to determine the lateral position of said heel end, the member 42 being mounted upon trunnions 222 on the lower ends of arms 224 which are mounted on pivots 230 to swingfrom side to side, this mechanism being operated as described in detail in said patent to carry the heel rest yieldingly into supporting and positioning engagement with the shoe and then to hold it in operative position. As the heel rest is moved up intoengagement with the shoe, any lateral displacement of the heel end the heel rest member 42 comprises oppositely ,7 i

of the shoe in unsymmetrical relation to the member 42 will cause the member .to be swung laterally by movement of the arms 224 about the pivots 230 and may'also cause the shoe to be swung reversely to some ex tent, until the shoe is seated centrally be tween the opposite diverging portions of the member. F or'the purposes of this in vention one of the-heel rest socket'members mounted onithe trunnion .222 is provided with a laterally extending arm 234' upon which is pivotally mounted an adjusting member 236 provided with a V-shaped recess or guideway having oppositevwalls 238 arrangedto cooperate w1th a pin240 mounted on the lower end of theadjacent arm 224, this arrangement being similar to the pin and guide arrangementfor the side gripper adjusting means. I 242on the arm 234 is arranged to engage in Vdifi'erent'depressions in the face of the member 236,.as shown in Fig. 12, .to hold the member in different adjusted positions.

is tipped downwardly until it engages the lower wall of the guideway 238, and that swinging movement of the arms in the op posite direction will cause the pin to engage A spring pressed plug the opposite wall of the guideway. When 7 the heel rest is in itscentral position the pin is located equidistantly from the walls of the guideway, the limiting means thus permitting the rest to be moved equal distances in opposite directions, the extent of such movements being varied in accordancewith the adjustment of the member 236. Positive limiting means is thus afforded to insure the correct angular relation of the last to the toe gripper for both the right and left shoes of any given style. All that the operator is required to do in order to cause the heel rest to perform its function properly is to position the shoe in the machine with the heel part deflected laterally in one direction or the other, accordingly as the shoe presented is'a right or a left shoe, a greater distance than required for the final position of the shoe, and when the machine is operated the shoe, by its engagement with the heel rest, will swing the rest laterally as far as permitted by the pin 240 and will then itself be swung into its correct location by the wedging action of the rest. While small changes in the swing of the last may be compensated for by adjustment ofeither the side grippers or the heel rest alone, it is contemplated that usually both the member 204 and the member 236 will be adjusted in order to avoid any exaggerateddisplacement of the grippers or of the .heel end of the last. If desired suitable marks may be provided to indicate corresponding positions of the different adjusting members.

The cycle of operations of the machine will be more fully understoodby reference to Fig. 13. After the work has been positioned in the manner hereinbefore described, the

side grippers closed and the machine started through the operation of the treadle rod 30, the cam 168 first releases the roll 166 and causes the gripper spreading mechanism shown in Fig. 7 to be withdrawn in such manner as'to permit rearward movement of the toe gripper. The rise a on the cam 80 then immediately becomes effective to swing the toe gripper backwardly, thus pushing the last rearwardly within-the. upper, this movement of the toe gripper being substantially or approximately completed before the gripper operating means becomes effective to close the toe gripper and to impart updraw movement to the grippers. Followingthe rearward movementof'the last to the point required, the toe and side grippers are operated to pull the upper. At the beginning of the updraw movement of the toe gripper the roll 92 encounters a depression Z) on the face of the ,cam 80, thus permitting the spring 116 to operate the gripper controlling means in such manner as to swing the toe gripperreversely in a forward direction, causing :it to clear the toe end of the last without objectionable engagement with the margin of thesole or insole'and also to impart a forward draft to. the portion of the upper extending over the top of the toe of the last. As the toe gripper continues its updraw movement, the wide portion of the plate 114 is pulled out of the slots in the'plugs 112 and the gripper is released to theaction of its overdraw springs to permit it to swing inward, as suggested in Fig. 1, during the latter portion of its updraw movement. The upper pulling movement of the grippers having been completed, the machine comes to rest at the point indicated by the arrows 0 on Fig. 13. a I

When the machine is again started the side clamp arms 13 are swung inward against the shoe, and the toe and side overlaying and tacking mechanisms are swung inward and operated in the usual manner, causing the grippers to release the upper, and then driving tacks to fasten the upper at the toe and the sides. At the point d (Fig. 13) a rise on the cam 80, arranged to operate during the inward movement of the tacker arms, causes the toe gripper controlling frame 106 to move the plugs 112 rearwardly for a short distance, and at the point e a further rise on the cam causes these plugs to be moved still farther rearwardly, this latter movement taking place substantially at'the time when the roll 166 encoun-. ters the cam 168 whereby the spreading mechanism (Fig. 7) is operated to return the grippers to their starting positions. By the action of this mechanism the toe gripper is moved outwardly to meet the plugs 112 and to aline the plate 114: with the slots in the plugs, the'plate sliding into these slots as the toe gripper moves downwardly in its return to starting position. The frame 106 havin thus been connected again to the toe gripper, the cam 80 at the point f causes the frame to be swung forwardly by the spring 116 and thus to .carry the toe gripperto its forward limit of movement ready for operation upon the next shoe.
